Design and research on a shape memory alloy-actuated single-port laparoscopic surgical robot

Abstract

With the development of minimally invasive techniques as well as surgical robotics, there has been an urgent demand for laparoscopic surgical robots that are small, low-cost and adaptable. This paper proposes a new design of minimally invasive surgical robot based on shape memory alloy (SMA)-actuated system which can provide flexible movement, large work space and powerful output. In the end, the performance of the robot system is conducted in vitro and in vivo tests.
